JACK FOR JOURNAL BOXES.

Specification of Letters Patent.

Patented Mar. *7, 1922.

Application filed February 15, 1921. Serial No. 445,153.

To all whom it may concern:

Be it known that CHARLES EDWARD RAI- BER, a citizen of the United States of America, residing at Salamanca, in the county of Cattaraugus and State of hew York, has invented new and useful Improvements in Jacks for Journal Boxes, of which the following is a specification.

The object of the invention is to provide a relatively simple, strong and etlicient means for raising railroad car journal boxes for the purpose of relieving the axles of the weight of the car body to permit of re pairs and replacements of the brasses or other bearing elements of the boxes and for like purposes, particularly necessitating the holding of the car wheels from being raised with the journal boxes; and with these objects in view the invention consists in a construction and combination of parts of which a. preferred embodiment is shown in the accompanying drawings, wherein:-

Figure 1 is a side View partly broken away of a ack constructed in accordance with the invention.

Figure 2 is a sectional view taken in the plane indicated by the line 2-2 of Figure 1.

Figure 3 is a section on the plane inclicated by the line 3-3 of Figure 1.

Figure 4 is a plan view.

Figure 5 is a sectional view of the pawl engaging member.

The jack consists essentially of a casing 10 having a base 11 adapted to rest upon a tie 12 or other substantial supporting surface, a shaft 13 mounted in suitable bearings 14: in the side walls of the casing, a forked lifting bar 15 straddling the shaft 13 and having at its upper end a head 16 for engagement with the journal box as indicated at 17, the shaft being provided with a pinion 18 meshing with a rack 19 formed on the inner-surfaceof one of the parallel arms of the fork and serving to raise the lifting bar when the shaft is rotated by suitable operating means indicated at 20.

In the construction illustrated the operating means consist of a ratchet wheel 21 fixed to the shaft 13 and an operating lever 22 fulcrumed upon the shaft with a yoke 23 straddling the ratchet wheel and carrying a pawl 24 for successive engagement with the teeth of the ratchet as the lever is oscillated to communicate movement to the lifting bar. Preferably the ratchet wheel is of a diameter considerably in excess of the pinion 18, and in order to lock the lifting bar in its elevated position a retaining dog 25 may be fulcrumed upon the casing as at 26 with a terminal transverse tooth 27 to lie between the arms of the lifting bar and engage the teeth of the gear 18. The dog 25 preferably extends through an opening in the wall of the casing and beyond the plane thereof to form a grip 28 to which pressure may be applied to disengage it from the gear to permit the lifting bar to return to its normal position.

As a means of holding the car wheel indicated at 29 from upward movement with the journal box as the latter is raised by the lifting bar a retaining arm 30 is mounted in a keeper 31 rising from the base of the casing and adjustably secured by a key 32, the said retainer and keeper being provided with series of openings 33 for selective engagement by the key to properly position the head 34 of the retainer in engagement with the flange of the'car wheel as indicated in Figure 1.

Having described the invention, what is claimed as new and useful is l. A car ournal box jack having a casing in which is reciprocably mounted a lifting bar for engagement with a journal box, and a retainer carried by the casing for engaging the flange of a car wheel, the lifting bar being forked to form parallel arms of which the inner surface of one arm is toothed, an operating shaft mounted in bearings in the walls of the casing and carrying a pinion straddled by the fork of the lifting bar and engaging the said teeth on an arm thereof, and operating means for actuating the shaft, a. retaining dog being mounted in the casing for engagement with said gear for locking the lifting bar in its adjusted positions and having a trip arm extending beyond the wall of the casing for actuation to release the gear.

2. A car journal box jack having a casing in which is reciprocably mounted a lifting bar for engagement with a journal box, and a retainer carried by the casing for engaging the flange of a car wheel, the lifting bar being forked to form parallel arms of which the inner surface of one arm is toothed, an operating shaft mounted in bearings in the walls of the casing and carrying a pinion pawl carried by the lever for engaging the straddled by the fork of the lifting bar and gear, a retainingdog being arranged in engaging the said teeth on an arm thereof, operative relation with the gear by which 10 and operating means for actuating the shaft motion is communicated to the lifting bar.

consisting of a retainer wheel fixed to the In testimony whereof he aflixes his signa- 7 operating shaft, an operating lever having ture. a fork straddling the ratchet gear, and a CHARLESVE. RAIBER
